Pretty sure my engine is a 1993 ST185RC. Is there a different code for that one listed?
(I had Dr. Tweak do a full harness for me specifically to mate to that ECU, so it's rather important that I get the right number to tell the guy to find)

I have to find out the specifics of the engine that was put in, but yeah, if anyone can list all the specific st185rc ecu numbers, that would rock.
And thank you for responding Fusselbug.

Mario I'm guessing it will be a different number. My car is later 92 and when I put the JDM ECU in several years ago (thought the ECU could be bad, it wasn't), I had to repin my harness because the JDM ECU was the earlier revision. If everything you have is for a 93, you'll need the later revision. Sorry I don't have the number.

The RC was only made during the 1991-92 model years. The ECU model numbers I listed are all of the JDM ECUs for 5th gen Alltracs. If your engine is from a '93 it was from a non-RC ST185.

This should have ECU pinouts for whatever 3SGTE you're working with:

Well, perhaps it is a 92 then. I don't know, I was told it is a '93. I do know, however, that it is an RC motor. The 5mm larger tb and afm alone denote that.
I will shoot over the ecu numbers and see if they match up. *fingers crossed*

I have the same info as fussellbug. here is the pinout that I have

Have to replace my ECU. Mine is 89661-2B280 which from my research is a 92 JDM.
I found one for sale that says its a 92 but its CND 89661-20760.
Comparing the pin out diagram I will have to move some pins but what about the missing or added pins? And the FC is on a completely different plug. Ugh!
Added:
EGR
TPC
STJ

It looks like the G- moves plugs as well, and TPC just scoots over a few pins. I know a lot of people delete EGR so you should be able to get around that one. The rest I'm not sure what those abbreviations mean.
